| Jul 23, 2017 at 10:54 | comment | added | Boaz Tsaban | @AlexanderOsipov Yes, the proof for $S_1(\Omega,\Gamma)$ is the same. Indeed, in courses I prove for $S_1(\Gamma,\Gamma)$ and then deduce for $S_1(\Omega,\Gamma)$ as an immediate consequence. | |

| Jul 23, 2017 at 6:54 | comment | added | Alexander Osipov | If I understood correctly, then this is true for any principle in The Scheepers Diagram ( Including the Borel covers ) ? | |
| Jul 23, 2017 at 6:48 | comment | added | Alexander Osipov | Thanks! I was more interested the principle $S_1(\Omega, \Gamma)$, but i find Gerlits-Nagy's result that $S_1(\Omega, \Gamma)={ \Omega\choose \Gamma}$. | |
